Fluid dispenser device of the multi-dose type
A fluid dispenser device a body ( 1 ), a fluid reservoir ( 3 ), a dispensing member, such as a pump or a metering valve having a piston or a valve member that is mounted to move axially, which dispensing member is fitted to the reservoir ( 3 ), and an actuating element ( 5 ) mounted to move between a rest position and an actuating position, for actuating the dispensing member and thus for selectively dispensing the fluid contained in the reservoir ( 3 ), fluid dispenser device being characterized in that the direction in which actuating element ( 5 ) moves is different from, and in particular perpendicular to, the axial direction in which the piston or the valve member of the dispensing member moves, the actuating element ( 5 ) having an end portion provided with the cam surface ( 6 ) which co-operates with the reservoir ( 3 ) or a fixing ring ( 8 ) adapted to fix the dispensing member to the reservoir ( 3 ) so that the actuating member ( 5 ) being moved substantially radially into its actuating position causes the reservoir ( 3 ) to be moved axially relative to the piston or to the valve member of the dispensing member so as to dispense a dose of fluid.
1. A fluid dispenser device comprising a body ( 1 ), a fluid reservoir ( 3 ), a dispensing member having a piston or a valve member that is mounted to move axially, which dispensing member is fitted to the reservoir ( 3 ), and an actuating element ( 5 ) mounted to move between a rest position and an actuating position, for actuating the dispensing member and thus for selectively dispensing the fluid contained in the reservoir ( 3 ), said fluid dispenser device being characterized in that the direction in which said actuating element ( 5 ) moves is different from the axial direction in which the piston or the valve member of the dispensing member moves, the actuating element ( 5 ) having an end portion provided with a cam surface ( 6 ) which abuts an abutting member which is movable and rides on the cam surface, the abutting member being coupled to the reservoir ( 3 ) or a fixing ring ( 8 ) adapted to fix the dispensing member to the reservoir ( 3 ), so that the actuating element ( 5 ) being moved substantially radially into its actuating position causes the abutting member to move along the cam surface and the reservoir ( 3 ) to be moved axially relative to the piston or to the valve member of the dispensing member so as to dispense a dose of fluid.
2. A device according to claim 1 , in which said cam surface comprises a sloping surface ( 6 ) and the abutting member comprises at least one projection ( 7 ) integral with the reservoir ( 3 ) or with the fixing ring ( 8 ).
3. A device according to claim 1 , in which said actuating element ( 5 ) is provided with return means for returning it from its actuating position to its rest position after each occasion on which the device is actuated.
4. A device according to claim 3 , in which the reservoir ( 3 ) and said dispensing member form a first unit, said body ( 1 ) and said actuating element ( 5 ) forming a second unit, said first unit being fixed into said second unit.
5. A device according to claim 4 , in which, after fixing of said first unit in said second unit, the end-wall ( 3 a ) of the reservoir ( 3 ) remains accessible for being actuated by hand by pushing axially on said end-wall of the reservoir.
6. A device according to claim 4 , wherein the first unit is fixed into the second unit by snap-fastening.
7. A device according to claim 1 , in which said dispensing member is a pump including a piston.
8. A device according to claim 1 , in which said dispensing member is a metering valve including a valve member.
9. A device according to claim 1 , wherein the dispensing member is at least one of a pump or a metering valve.
10. A device according to claim 1 , wherein the actuating element moves perpendicular to the axial direction in which the piston or the valve member of the dispensing member moves.
11. A fluid dispenser comprising:
a body;
a fluid reservoir;
a dispensing member fitted to the reservoir and movable in an axial direction; and
an actuating element which is moved between a rest position and an actuating position to actuate the dispensing member;
wherein, the direction in which the actuating element moves is different from the axial direction in which the dispensing member moves;
wherein the actuating element comprises a cam surface which abuts an abutting member and the abutting member moves in response to actuation of the actuating element.
12. The fluid dispenser of claim 11 , wherein the abutting member is coupled to at least one of the fluid reservoir and a fixing ring which fixes the dispensing member to the reservoir.
13. The fluid dispenser of claim 12 , wherein the abutting member is movable along the cam surface, so that when the actuating element is actuated, the abutting member moves along the cam surface and the reservoir is moved axially relative to the dispensing member so as to dispense a dose of fluid.
14. The fluid dispenser of claim 13 , wherein the cam surface is a sloped surface.
15. The fluid dispenser of claim 9 , wherein the cam surface has a varying gradient.
16. The fluid dispenser of claim 13 , wherein the actuating element moves perpendicular to the axial direction in which the dispensing member moves.
17. The fluid dispenser of claim 13 , wherein the dispensing member comprises a piston or a valve member and the abutting member comprises a projection.
18. The fluid dispenser of claim 13 , wherein pressing a surface of the reservoir also actuates the fluid dispenser to dispense a dose of fluid.
19. The fluid dispenser of claim 11 , wherein the abutting member moves relative to the body.
20. The fluid dispenser of claim 11 , wherein the abutting member remains axially fixed relative to the reservoir during actuation of the actuating element.
